Steel shear walls with corrugated plates (SSWCP) is a new widely used technique to resist the lateral forces in the high-rise buildings. Ultimate capacity of the SSWCP is investigated in this research using finite element models and comparison with flat plate shear walls is achieved. Three-dimensional models using shell elements for both infill plate and boundary frame are used. Several geometrical parameters control the results such as infill plate thickness, corrugation density, corrugation dimensions, corrugation orientation and boundary frame geometrical properties. Using corrugated steel plate in shear walls affects directly the shear wall capacity. Corrugated plate shear walls not necessarily have higher ultimate capacity more than flat shear walls. Vertically oriented corrugated shear walls have higher capacity than other orientations but it may have less stiffness compared with the inclined corrugated shear walls. Changing the orientation of the corrugation affects the ultimate bearing capacity of the shear wall. It is found that trapezoidal corrugated infill plate has better performance than the sinusoidal corrugated infill plate as well as less cost and weight. Updating the critical buckling stress formula for trapezoidal corrugated shear walls taking into consideration several parameters is included in this research.

The system that resists this force must be economically designed. Several systems are used to resist lateral loads such as moment frames, braced frames Al-Azhar University Civil Engineering Research Magazine (CERM) Vol. (41) No. (3) July, 2019
